I just updated to 8814 and get the following error when trying to load a game. When I try to ignore the error, the game just reverts back to the start screen:
DEBUG : Error: line 161:19: no such item group
},
{
"group":
^
"raw_materials",
"chance": 100,
"repeat": [ 2, 5 ],
FUNCTION : bool main_menu::load_character_tab()
FILE : src/main_menu.cpp
LINE : 964
Update: I reverted the build a few steps at a time, and it seems the culprit is build 8806. The error persists from thereon, but I can load the save just fine on build 8805.
